To @ZZ whom tm/ty concern.:

Beitknown thatwe, JOHN J. BOUCHARD and WILLIAMjF. ENSOR, citizens of the United States, and residents of Bradford, in the county of McKean and State of Pennsylvania, have invented a new and Improved Trolley- Stand, of which the following is a full, clear, and exact description. f

Our invention relates to improvements in stands for the trolley-poles of electricallydriven railway-cars.

In the present invention we seek to produce a simple and substantial construction of the mechanism constitutingthe-bearing around which the pole may swing or turn on a verti-A cal center, said mechanism being so designed as to'mmimize the friction` and wear on the working surfaceato. turn easily and freely without lubrication, and to exclude the eni on the line 3 3 of Fig. 2.

trance of dust and dirt from" the working parts. We also seek to produce a construction which providesv for the secure attachmentof the pole to the pole-socket in a way to relieve the strain on the pole-clamp and to allowthe ready interchange of different Further objectsand advantagesV of the invention will appear in thecourse of the subjoined description, andkthe novelty will be defined by the'annexed claims..

Reference is to be had tothe accompanying drawings, forming a partof this specification, in which similar characters of reference indicate corresponding parts in'allthe figures.

Figure 1 is a side'elevation of atrolley-stand constructed in accordancewith our invention. Fig. 2 is a plan View thereof. Fig. 3 is a longitudinal central sectionthrough the stand Fig. 4 is an enlarged sectional view through one of the antifrictionbearings, and Fig: 5 is a plan View of said bearing.

5 designates abase-plate which is provided with a central Vthreaded opening 6, in which is screwed the lower threaded end 7 of a short vertical post 8. This `post is equipped with one or more antifriction-bearings 9 ot' the type shown more particularly by Figs. 4 and 5, and these bearings support a shell or casing 10, adapted ,to inclose the bearings. The shell `disposed in pairs. Vposite sides of the divided tube are coupled `by bolts28, having suitable nuts 29, and by tightening these nuts the bolts are adapted 4or casing is provided with horizontal arms 11, which project from opposite sides thereof, said arms being integral with the casing. The arms support or carry a horizontal pivuotal shaft 12, on which is mounted a yoke 13,

said yoke being cast in one piece with a tube or sleeve 14, adapted to form a socket for the trolley-pole 15, and the arms of said yoke 13 are provided with depending lugs 16. To these arms are pivoted the rods or bolts 17, which lie on opposite` sides of the casing or housing and have their other ends fastened to a crosshead 1S, the same being slidably fitted on a guide-tube 19, which is secured in a boss 20, cast in one piece with the casing or housing. The cross-head 18 is pressed in one direction by a strong coiled spring 2l, loosely fitted on the guide tube or rod 19, and one end of this spring is seated against the boss 20, While its other end acts against the slidable cross-head 18. The movement of the ,cross-head in one direction is limited by a nut 122, screwed on the outer end of the guide tube or rod 19, and against this stop-nut acts a check-nut 23, also screwed on the guide-stem afforded by the tube or rod 19.

The tube 14 is provided with a socket 24, `audsa'id tube is also split or-divided for a part of its length, as indicated at 25 in Fig. Q1, thereby forming a pair of coperating .grippingjaws 26 at the free ends of said tube `514. The slit or division does not extend the full length of -the socket 24 in the tube .14, andthe jaws 26 of said tube are provided on opposite sides with the lugs 27, which are The pairs of lugs on opto draw the lugs together in a way to compress the jaws 26 on the trolley-pole 15. This pole is fitted in the socket 24.0f` the tube to extend beyond the inner end of the division 25, and the pole thus has a solid bearing against the tube 14, which relieves the bolts. The nuts may be 28 of considerable strain. readily loosened to releasethe gripping-jaws from the pole 15, which can be easily withdrawn, after which another pole can be inserted in the socketed tube and confined IOO therein by the clamp, consisting of the jaws and the bolts. y Y

Each antifriction-bearing 9 is constructed as indicated by Figs. 4 and 5, in which 30 designates a cylindrical shell having an internal conical track-surface 31. A tubular bushing 32 is fitted in this shell concentric therewith, and said bushing is provided with an external track-surface 33, which is in opposing relation to the surface 31 of the cylindrical shell. An adjusting-ring 34 is screwed in the upper open end of the cylindrical shell 30, and said ring is provided with an inner conical surface 35. The ring 34 is made fast with the shell 30, and a similar ring 36 is made fast with the bushing 32 by screwing it on the male-threaded upper end of the bushing, said ring 36 having an external couical surface 37, which is in opposing relation to the internal conical surface 25 of the ring 34. An external gear-ring 38 is fitted on the bushing to reston the ledge formed by the track-surface 33, and this gear-ring is clamped in place by the track-ring-3G, which is fixed to the bushing 32. An internal gear-ring 39 is fitted on the ledge afforded by the tracksurface 31 of the cylindrical casing, and it is held in place by the adjusting-ring 34, which is screwed within the casing 30, the gearrings 38 39 being concentric and disposed in opposing relation.

40 designates a series of spindles, which carry the conical bearing-rollers 41 42, the rollers 41 being disposed between the tracksurfaces 31 33 of the casing and the bushing, while the rollers 42 are confined between the track-surfaces 35 and 37 of the adjustingrings 34 and 36, which are attached to the casing and the bushing, respectively. These spindles 40 are also provided with the gearpinions 43, which mesh with the gear-rings 38 and 39 of the bearings, thus positively turning the spindles and the friction-rollers carried thereon.

The lower bearing 9 is iitted to the short post `8 by slipping the bushing 32 thereon, and

casing.

this bushing rests upon a washer 44, below which is arranged a packing material 45, which in turn rests upon another metallic vwasher 47, that engages directly with the top face of the base, the latter having a boss 5a, which extends into the lower open end of the surrounding casing 10. The metallic washers and the packing t snugly within the lower part of the cylindrical casing 10, so as to exclude the admission of dust and moisture to the bearing. AOn top of the lower bearing 9 is seated a spacing ring or collar 48, which incloses suitable metallic washers 49 and 50, and on the upper washer 50 and the spacingring 48 rests the bushing and shell of the up per bearing 9. The adjusting-rings 34 36 of this upper bearing9 are provided with notches er sockets 51, and the casing 10 is provided with an internal ledge or shoulder 52, the latter` being disposed near the upper part of said This ledge or shoulder is provided The post S extends through the two bearings 9 and into the upper part of the casing 10, and on the upper bearing 9 rests a spacing-sleeve 55, the upper edge of which is engaged by a metallic washer 56, adapted to support apackiug material 57 and another metallic washer 58. On the upper extremity of the post Sis screwed a clamping-nut 59,

which bears against the washers 56 58 and the packing material and exerts pressure on the spacing-sleeve 55, the latter resting on one of the adjusting-rings ofthe upper bearing 9.

It will be observed` that the two bearings 9 have theirbushings 32 itted on the post 8, andthe nut 59 is arranged to clamp thecentral parts ot' these bearings9 firmly to the posts, While the shells 30 of the bearings are loosely supported on and around the posts, so as to rotate freely thereon. The shells 30 of the upper and lower bearings are fitted snugly in the external casing or housing 10, which is made fast with the upper bearing, and this external casing or housing is supported by the antifriction-bearings and the post in a way to raise the lowerl edge of the casing or housing 10 from engagement with the baseplate. 5, thus minimizing the friction-and wear on the working parts. The employment of the .packing materials 45 57 in the upper and lower parts ot' the casing 10 exclude the admission of dust and moisture to the antifriction-bearings, and the revoluble support forv the pole 15 is free to turn on a .vertical axis, owing to the presence of the 'the pole 15, together with the tension devices therefor, are supported wholly by the casing vor housing 10, which is free to turn on the vertical axis aorded by the stationary post 8.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In a trolley-stand, the combination of a non-revoluble post, a casing provided with au inwardly extending shoulder and fitted loosely around the post, an antifriction-bearing having a member clamped to said post, and an external member revoluble freely within said casing, said bearing also having an interposed roller.- supported wear-ring which is made fast with the shoulder of the casing, the entire casing being supported by the parts of the antifriction-bearing.
